Polyarticular Heterotopic Ossification Complicating Drug-Induced Coma

The authors describe a case of generalised heterotopic ossification (HO) complicating the clinical course of a 31-year-old male patient with a history of Hodgkin’s lymphoma and of long stay in an intensive care unit, where he had been placed in an artificial coma. The clinical features, as well as radiological findings and therapy, are discussed.
